[OpenSIPS-Users] restart_persistency Permission denied

[Marcin Groszek]

Centos 7 opensips verion 3.1.5

I attempted to setup drouting restart_persistency but as soon as I add 
these 2 lines:

restart_persistency_size = 512

modparam("drouting", "enable_restart_persistency", yes)

opensips does not start.

The logs shows:

ERROR:core:rpm_init_mem: could not initialize restart persistent memory!
ERROR:drouting:dr_init: could not initilize restart persistency memory!
ERROR:core:init_mod: failed to initialize module drouting
ERROR:core:main: error while initializing modules
ERROR:core:init_rpm_mallocs: could not create the restart persistency 
memory file .restart_persistency.cache (13: Permission denied)

Thank you.
